Why Am I here?

When I find I've got nothing to do, I ask myself "Why Am I here?" Well, the next few hours are peacefully spent thinking about various reasons I could've been sent onto earth for.
But seriously, if you think about it thats one of the most difficult questions to answer. We are born, go to school, make little friends, grow up to go different ways and finally end up getting married and leave the world with much less funfare than we actually came here with. Do the little moments of happiness and tears carry any meaning when we are gone? What happens when we are gone? Does someone remember us unless we are maybe an Elvis Presley or Marilyn Monroe? How significant is their contribution to society than that of people who've worked years to make things better. The scientists, the doctors, the engineers, architects who built or helped to build the world around us. No wonder that we remember that Shah Jahan built the Taj Mahal, but we conveniently forget the architect, Ustad Ahmad, who built it or the countless people who worked to make it happen.
So ask yourself "Why Am I here?" and lemme know your comments!
